Call Routing IDC or Global

[armytechie]

Not really sure how to pose this question quickly but I'll try

We have two providers currently MCI and Verizon both providers have assigned us an 8xx numbers along with the DNIS.
example
MCI DID MCIDNIS 8xx
646-227-1234 1234 866-232-4453

Verizon DID Verizon DNIS Verizon 8xxx
212-324-4321 9876 800-435-7654

The two above point to Concerto DNIS 5400
I have concerto and symposium

The question is. where is it controlled if lets say I lose MCI or Verizon or even concerto or syposium and need to reroute the traffic? Is the translation global or bound to a circuit? How is it I can have the switch or the 800 numbers routed to the equipment that is functioning and not lose the associated DNIS

Good question! If your provider re-routes over PSTN you will not receive DNIS. However, if your DID number matches your DNIS you can still route that call by the IDC table. But as for true DNIS, not going to happen.
